SDET

Software Development Engineer in Test: an engineer who builds test automation, tooling, and quality infrastructure.

Glossary

What is SDET?

What is SDET?

An SDET, or Software Development Engineer in Test, blends software engineering with quality expertise—writing automated tests, building test frameworks and tooling, and integrating quality checks into the delivery pipeline. Unlike a purely manual tester, an SDET codes, and unlike a pure developer, their focus is testability and reliability. SDETs are the people who make continuous testing possible at scale. Tools that generate clean, ownable Playwright code and cut maintenance let SDETs spend their time on strategy and coverage rather than fixing brittle selectors.
